Background for this topic.
Evasion is the deliberate concealment or modification of malicious code, commands, traffic, or behavior to bypass security controls and avoid detection. Common examples include code obfuscation, encrypted or rapidly changing payloads, abuse of trusted system tools, and disguising command-and-control traffic as ordinary network activity. It can target antivirus signatures, email and web filters, endpoint monitoring, or analysts investigating suspicious activity.
Successful evasion can reduce visibility, delay detection, and allow unauthorized activity to continue, although it may still leave behavioral or operational evidence. Mitigation should combine signature detection with behavior-based analytics and reliable endpoint, identity, and network telemetry. Restricting unnecessary scripting and administrative tools, applying application controls, and protecting centralized logs make abuse harder and preserve evidence. During investigations, examine process ancestry, unusual tool use, persistence changes, and deviations from expected user or host behavior rather than relying solely on file hashes or other easily changed indicators.

You don't need us to craft phishing emails or write malware, super-lab sniffs OpenAI has shut down five accounts it asserts were used by government agents to generate phishing emails and malicious software scripts as well as research ways to evade malware detection.…
That means Brit spies want the ability to do exactly that, huh? The idea that AI could generate super-potent and undetectable malware has been bandied about for years – and also already debunked. However, an article published today by the UK National Cyber Security Centre (NCSC) suggests there is a "realistic possibility" that by 2025, the most sophisticated attackers’ tools will improve markedly thanks to AI models informed by data describing successful cyber-hits.…
